Four-year-old pug and beagle cross Barney is brought into Fitzpatrick Referrals after being hit by a bus. The dog has lost 40 per cent of the bone in the damaged leg, so Noel creates an innovative two-tier treatment, involving an external ankle frame for support. Sisters Rosemary and Diane bring in their five-year-old basset hound Albert when they find he is suddenly unable to move his back legs, and 10-month-old Labrador cross Gylly receives treatment for lameness and an unusual bone deformity.
